Issue when adding scene as reference/payloads - Materials Strength is modified

Omniverse General Discussion

Hi!

When I add a USD scene as a reference or payload, some prims in that scene have their Strength attribute (Property → Materials on selected models) changed from Weaker than Descendants to Stronger than Descendants.

The actual USD scene is the USD EXPLORER SAMPLE 3D MODELS PACK.

Any idea why ? I’d like to avoid having to change this setting manually in case this also happens for other projects.

Thanks!

Hey Felix,

I tried a few models from that pack and did not observer this behaviour. What models specifically and what version of Composer or Explorerer are you using?

Hi Charles,

It was with the Factory.usd : ‘…\ov-usdexplorersamplespack-01-100.1.0\Usd_Explorer\Samples\Examples\2023_2\Factory\Factory.usd’

And this issue appears on the prims : /World/Factory/Samples and /World/Factory/Stage.

I’ve tried with USD Composer 2023.2.0 / 2023.1.1 and 2022.3.3.
